Spiders in Seattle: What You Need to Know
Seattle, Washington, like many parts of the Pacific Northwest, is home to a diverse range of spider species. From harmless house spiders to potentially dangerous hobo spiders, understanding the types of spiders you might encounter can help you navigate your arachnid interactions.
Common Spiders of Seattle
Seattle’s spider population includes both native and introduced species. Some of the most frequently seen spiders include:
House Spiders
Several species of house spiders are common in Seattle homes. These spiders are generally harmless to humans and can even be beneficial, as they prey on other insects. They often build webs in corners, under furniture, and in other undisturbed areas.
Hobo Spiders
Hobo spiders are a type of funnel-web spider found throughout the Pacific Northwest. While their bites were once thought to cause necrosis, more recent research casts doubt on this. (Learn more about hobo spider on Wikipedia). Their bites can still be painful and cause localized symptoms.
Wolf Spiders
Wolf spiders are large, hairy spiders that are active hunters. They don’t spin webs but instead chase down their prey. While they can look intimidating, they are not considered dangerous to humans, although their bite can be painful.
Orb-Weaver Spiders
Orb-weaver spiders are known for their intricate, circular webs, often seen in gardens and wooded areas. These spiders are beneficial predators that help control insect populations. They are generally not aggressive and will only bite if threatened.
Giant House Spider
Related to the hobo spider, the giant house spider is another common sight inside homes in Seattle. They are fast runners and can be quite large, which might be startling, but they are not considered dangerous to humans.
Are Seattle Spiders Dangerous?
The vast majority of spiders in Seattle are not dangerous to humans. While spider bites can be painful, most are no more harmful than a bee sting. Hobo spiders are the species that cause the most concern. It’s always a good idea to seek medical attention if you suspect you’ve been bitten by a spider, especially if you experience severe symptoms.

Several steps can be taken to minimize the presence of spiders in your home:
- Seal cracks and crevices in your foundation and around windows and doors.
- Remove webs and egg sacs regularly.
- Keep your home clean and clutter-free.
- Reduce outdoor lighting, which can attract insects that spiders feed on.
- Consider using natural spider repellents, such as peppermint oil.
